Guadalajara, May, 1891 (n. 5147). I am indebted to Mr. Hemsley 
for the information that this plant is distinct from £2. conferta, 
Benth., and that it appears to be the same species as Seemann’s 
2189, collected in the Sierra Madre. In the Gray Herbarium 
there is a similar plant collected by Seemann in the Sierra Madre, 
and probably representing his 2189. It certainly seems to be spe- 
cifically the same as Mr. Pringle’s plant, although it represents a 
somewhat different stage of growth. In it the leaves arise from 
the stem, and the inflorescence is hirsute and less glandular. In 
Mr. Pringle’s plants the stem-leaves have all fallen, and the entire 
foliage is crowded upon short secondary axes, giving the specimens 
a rather different habit. 
VIGNA LUTEOLA, Benth., var. ANGUSTIFOLIA. Stem appressed- 
pubescent: leaflets lance-linear, rounded at the base, 14-2 inches 
long, about 3 lines broad: petioles short, not an inch in length.— 
Wet places near Guadalajara, May, 1890 (n. 3488). 
VIGNA STROBILOPHORA. Stem slender, flexuous, branched, coy- 
ered with a fine soft pubescence: leaves pinnately trifoliate; leaf- 
lets ovate, acuminate, entire, rounded at the base, pubescent or 
glabrate above, somewhat paler and soft-pubescent beneath, 24 
inches long, half as broad; common petioles pubescent, 1} inches 
in length: peduncles axillary, rather stout, curved, bearing the 
flowers in dense racemes: bracts large, ovate, sharply acuminate, 
entire, scarious, finely striate, somewhat pubescent and ciliated 
toward the apex, closely imbricated over the buds, deciduous: 
pedicels single, silky-pubescent, 1-3 lines long: calyx campanu- 
late, short, colored; teeth short and obtuse: corolla blue-purple, 
6-7 lines in length; standard orbicular, slightly retuse, with two 
seale-like appendages at the base; wings bluntly auriculate on the 
upper side; keel bent nearly at right angles, the end then conspic- 
uously curved inward: stamens diadelphous: style bearded on the 
outer side near the end; stigma somewhat oblique. — Bluffs of 
barranca near Guadalajara, September, 1891 (n. 5163). This spe- 
cies is strongly characterized by its large closely imbricated 
bracts. In its keel it is almost intermediate between Phaseolus 
and Vigna. 
CSALPINIA MULTIFLORA, A medium-sized tree, minutely seri- 
ceous on the younger parts: foliage and racemes crowded near the 
ends of the branches; leaves 7 inches or more in length, bipinnate; _ 
pinne about 10 pairs; common petiole striate-suleate, 3 inches 
long; leaflets 15-18 pairs, elliptic-oblong, mucronate, entire, mod-- : a
